Abstract

The assessment of deep-seated rock in terms of engineering geology and geotechnology with respect to its suitability as a host rock for a final repository for radioactive waste requires the knowledge of the in-situ behavior of the rock in particular the stress and deformation behavior as well as the knowledge of permeability. The waterpercolation through fissured granite and the stress field is being studied in a Swiss German cooperation by the Federal Institute for Geosciences and Natural Resources (BGR) in the Grimsel Rock Laboratory in Switzerland. This laboratory is operated by the National Corporation for the Storage of Radioactive Waste (NAGRA) of Switzerland. German participants are the BGR and the Research Centre for Environmental Sciences (GSF). BGR is responsible for the Fracture System Flow Test (BK), a modified water injection test and advanced Rock Stress Measurements (GS) in deep boreholes.

Target of both projects is the development of methods and instruments.

In the presentation, some of the results of the stress and permeability measurements will be used to discuss the methods.

Résumé

L'estimation géologique et géotechnique d'une roche située, en profondeur en ce qui concerne sa qualification en tant que roche d'accueil pour le stockage final de déchets radioactifs exige la connaissance du comportement de la roche in-situ, particulièrement le comportement mécanique et la connaissance de la perméabilité. La percolation de l'eau à travers du granite fissuré et l'état des contraintes primaires sont examinés par une coopération suisse-allemande (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) dans le laboratoire souterrain du Grimsel/Suisse. Le laboratoire est exploité par la Société Coopérative Nationale pour l'Entreposage de Déchets Radioactifs (Cédra)/Suisse. Les participants allemands sont le BGR et la Gesellschaft für Strahlen- und Umweltforschung mbH (GSF). Le BGR est responsable pour les essais de perméabilité (BK), un essai modifié d'injection de l'eau et pour les mesures de l'état des contraintes primaires (GS) dans les forages profonds.

L'objectif des projets est le développement non seulement des techniques de mesures mais aussi des dispositifs d'essais. Les techniques appliquées et les résultats de mesures de l'état des contraintes primaires aussi bien que des essais, de permeabilité sont exposés dans le texte.
